I'm very new to Dolphin, I only discovered it less then 1 week ago! its gr8!

I'm running a ArchLinux64 setup and I managed to get it working pretty well for now. however I'm having a very anoying problem that makes the gameplay very hard:
I'm always losing the window focus, so basicaly, tha game is always stoping, because when the window loses focus it stops the game:S!

I still see the window selected, but for some stupid reason it acts like it isnt focus, so I have to be always messing around with the mouse, clicking and so on!

I have closed EVERY window, every application and it still happens !

Some help would be very appreciated! I've goggled a lot and I've found nothing..:S
